摘　　要：针对电磁调速电动机模拟控制器调速精度低、零点调整不方便等问题,文章设计了一种以AVR单片机为核心的全数字式电磁调速电动机控制器,介绍了该控制器的结构、硬件及软件设计,详细阐述了控制器过零检测电路、可控硅触发电路、脉冲转换测量电路的设计要点。该控制器采用频率测速和数字PID算法,可以满足不同负载的调速要求。Aiming at the problems of low precision of speed regulating and inconvenience of zero adjustment of analogical controller of electromagnetic speed regulating motor, the paper designed a fulldigital controller of electromagnetic speed regulating motor which took AVR single-chip microcomputer as core, introduced structure, hardware and software design of the controller. It also expounded the key point of design of detection circuit of voltage zero-crossing, thyristor trigger circuit and measurement circuit of pulse conversion in details. The controller applied speed measuring with frequency and digital PID algorithm, and could meet different load.
